This is a Kensington silver plate flatware set for six... probably 1920s vintage, NOT the International 'Kensington' pattern nor the Rogers 'Kensington' pattern, but an unknown (to me) pattern marked Kensington silver plate, as shown. Not Sheldon, not LaSalle. That's the only two Kensington patterns I know!
Very pretty, and apparently, hard to find! This set shows some surface scratching and wear from use, though very minimal wear to the plate.
If you know anything more about this pattern (what International silver called this when they almost certainly acquired Kensington at some point during the 20th century, or even what Kensington called it to begin with) please email me, I'd love to hear from you!
